McGinnis sacrificed himself in an act of supreme bravery on Dec. 4, belying his status as the youngest Soldier in Company C, 1st Battalion, 26th Infantry Regiment, attached to the 2nd Brigade Combat Team, 2nd Infantry Division.

The 19-year-old amateur mechanic from Knox, Pa., who enjoyed poker and loud music, likely saved the lives of four Soldiers riding with him on a mission in Baghdad.

McGinnis was manning the gunner’s hatch when an insurgent tossed a grenade from above. It flew past McGinnis and down through the hatch before lodging near the radio.
